Preterm labor is labor that occurs between the 22nd and 37th weeks of pregnancy. Premature babies have a higher mortality and morbidity rate than full-term babies. Therefore, prevention and treatment of preterm labor - threatened preterm labor is an issue that needs attention.

Premature birth is the leading cause of death in newborns. There are many causes of premature birth, some of which are preventable and pregnant women need to be aware of and prepare carefully to prevent this risk. There are many drugs that can prevent premature labor, but the results are not always successful, so prevention is better than treatment.
